Just playing a little bit of devils advocate here but why make your own chassis? Why not just use the OEM chassis and add components to it? I've seen that Tekno is doing the same thing (coming out with their own chassis) and I've been a little confused as to why...

I will say, that I've never replaced the chassis in my (old, 3 seasons) E-Truggy so I don't think it much matters either way.
